SLIDING-DOOR STOP AND FASTENER.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed October 20, 1908. Serial No. 458,718.

To all whom it may concern:

Be it known that I, GiLsoX I'IOMAX, a citizen of the United States, and resident of the city of Passaic, in the county of Iassaic and State of New Jersey, have invented a certain new and useful Sliding-Door Stop and Fastener, of which the following is a specification.

My invention relates to improvements in stops for the doors of railroad cars and particularly for that class of doors now in common use upon the sides of freight and livestock box cars, and the object of my invention is to provide a stop which will hold the door securely in the desired position, either tightly closed or partly opened for ventilation as may be desired, and which will so hold the door that it cannot be opened without detection and at the same time proride a cheap and eiiicient device of few parts which will not present difficulties in adjustment or in the replacement of injured parts.

I accomplish this object by the device illustrated in the accompanying drawings, in which Figure 1 is a view of the device complete with the door open, Fig. 2 is a view of the locking leaf, Fig. 3 is a view of the socket member, Fig. at is a view of the rear edge of the door with the locking leaf in its locked position, parts of the car and socket member being cut away.

Similar reference characters refer to similar parts, throughout the several views.

Upon the edge section of the sliding door 1 of a railroad car 2 or similar device I secure a retaining member 3 by means of bent over ears 4:, 5, 6 and screws or bolts inserted therethrough into the door. Upon this retaining member 3 I secure the locking leaf 7, rotatable thereon, by means of a pivot bolt 8. This locking leaf 7 is provided with an upwardly projecting lug 9, preferably integral therewith and having therein a series of apertures 10, 11, 12 corresponding to a similar series of apertures pierced in the upwardly projecting lug 13 on the retaining member 3, and is also provided with a backwardly projecting hook section 18 atthe rear of its lower edge section. I provide in the face of the car a series of sockets or pocket members 14, 15 preferably of iron or other suitable metal and having an inwardly extending pocket section 16 and a flaring lip section 17, the inwardly extending pocket 1 section 16 being covered over at one end 19 to engage the hook section lb of the retaining leaf 7 whereby the door 1 is held against outward swing. These pocket sections or in the side of the car 2 in the horizontal plane of the locking leaf 7. I prefer to so place two of these socket members a few inches apart, one of them at the point where it will lie directly under the locking leaf 7 when the door 1 is entirely closed and the other a few inches from the first so that the locking leaf '7 will lie directly over it when the door 2 is opened sufficiently for ventilation.

My device being thus assembled and the sliding door 1 having secured to its rear edge the retaining member 3 carrying the locking leaf 7 pivoted thereon at 8, and the door being closed, the locking leaf 7 will be directly over the open pocket of the socket member 1 1 so that the locking leaf 7 may be turned or pressed down into the said pocket 16 of the socket member 1a and one of the apertures 10, 11 or 12 will register with the corresponding aperture in the retaining member 3, when a pin 20 may be inserted into the said apertures thus securely holding the locking leaf 7 against displacement, and the backwardly projecting hook section 18 of the leaf 7 will hook into the covered section of the socket member 14:. 21 is preferably formed in the pin 20 to receive the usual seal wire or any desired form of lock or other device to be inserted therein so that the door 1 may not be opened without detection. The door 1 may be similarly locked in a partly open position by means of a socket member 15, similar in all respects to the socket member 14 above described, previously placed at the desired position in the face of the car.

While I have described my improved device secured to the rear of the door, it is obvious that it may be used to equal advantage at the front of'the door and where double doors are used one of my improved stops may be used on the front edge of one door and another on the rear edge of the other door, thus locking either door as may be desired.

Having thus described my invention what I claim is:

1. In a device of the character described, the combination of a structure provided with members 1-1- are placed at suitable intervals An aperture a doorway, a sliding door thereon, a socket member inserted in the structure at one side of the doorway and having a section adapted to be engaged by a locking plate, and a locking plate secured to the edge of the door and adapted to swing at a right angle thereto to engage the socket member and comprising sheetof metal having a pivot seat and a locking lug in one end section and having an apertured off set lug formed at the other end, a retaining member secured to the edge of the door and having an apertured ofl set lug normally lying adjacent to the ofl set lug on the locking plate so that the apertures thereof will register to receive a pin and a pivot bolt within the pivot seat of the locking plate and secured within the retaining member, substantially as shown and described.

2. In a device of the character described a i l l l l structure provided with a doorway, a door adapted to slide thereon, a socket member inserted in the structure at one side of the doorway, and comprising a socket section and a lip section, and adapted to be engaged by a locking plate carried by the door, a locking plate having a cut out section at one end to receive a section of the socket member and provided with a projecting apertured i11 and a member u )on the door also havin :3 b

a projecting apertured lug adaptedto register with the lug upon the locking plate, substantially as shown and described.

Signed at Passaic in the county of Passaic and State of New Jersey this fourteenth day of October A. D. 1908.
